What is a river for kids?
A river is a flowing, moving stream of water.
Usually a river feeds water into an ocean, lake, pond, or even another river.
Rivers can vary in size and there is no hard definition or rule on how big a flow of water must be to be categorized as a river..
What happens when a river overflows its banks?
A flood occurs when a river bursts its banks and the water spills onto the floodplain. Flooding tends to be caused by heavy rain: the faster the rainwater reaches the river channel , the more likely it is to flood. … Drains and sewers take water quickly and directly to the river channel.

How can you tell the age of a river?
Scientists look at various geologic clues to help determine the age of a river, including how old the valley surrounding it is, how deep the water cuts into the riverbed, and the age of the sediments carried by the river.
What is the beginning of a river called?
headwatersThe place where a river begins is called its source. River sources are also called headwaters. Rivers often get their water from many tributaries, or smaller streams, that join together.
What is the middle of a river called?
The middle of a river’s journey, when it gets wider and slows down, is called the middle age. Rivers often meander (follow a winding path) along their middle course.
Where does a river start and end?
Eventually a river meets the sea and the place where it does is called the mouth. The last of the mud is deposited at the river’s mouth. A wide mouth is called an estuary.
What are the 3 stages of a river?
3 Stages of a RiverYOUTHFUL STAGE (UPPER COURSE) – V- Shaped Valley > Erosion. … MATURE STAGE (MIDDLE COURSE) – Meanders > Erosion and Deposition.OLD AGE STAGE (LOWER COURSE) – Floodplains > Deposition. … Advantages. Scenic Attraction. … Dangers. Flooding – Damage to property, land, animals and homes. … Advantages. … Disadvantages.
What is the end of a river called?
deltaThe end of a river is its mouth, or delta. At a river’s delta, the land flattens out and the water loses speed, spreading into a fan shape. Usually this happens when the river meets an ocean, lake, or wetland.
When a river overflows its banks is called?
Floodplains The area along a river that forms from sediment deposited when a river overflows its banks is called a floodplain.
When a river overflows What causes it?
Rivers can overflow their banks to cause flooding. This happens when there is more water upstream than usual, and as it flows downstream to the adjacent low-lying areas (also called a floodplain), there is a burst and water gets into the land.
What problems can rivers cause?
Since the second world war, rapid population growth, urbanisation and demand for increased and cheaper food production have damaged natural river systems, causing many problems, such as water pollution, increased flood risk, loss of biodiversity and soil erosion.
What is the old stage of a river?
DeltaDelta (Old stage): • It is a triangular shaped piece of land formed at the mouth of a river. The river drops its load. If the sea is unable to remove it, it builds up.
What are the two ends of a river called?
The headwater can come from rainfall or snowmelt in mountains, but it can also bubble up from groundwater or form at the edge of a lake or large pond. The other end of a river is called its mouth, where water empties into a larger body of water, such as a lake or ocean.
What are the parts of a river?
Rivers are split up into three parts: the upper course, the middle course, and the lower course. The upper course is closest to the source of a river. The land is usually high and mountainous, and the river has a steep gradient with fast-flowing water. There is a lot of vertical erosion and weathering.
Does a river ever end?
Rivers “end” at larger bodies of water. … They don’t end on land, they end in a larger body of water (another river, a lake or, ultimately, the ocean). They start on land and flow to the ocean.
What is the largest river in the world?
Amazon RiverThe Amazon River is 3,980 miles (6,400 kilometers) long, according to the U.S. National Park Service. It is, however, the world’s largest river by volume and contains 20 percent of the Earth’s fresh water, according to the National Science Foundation.
